Had a coilpack go yesterday afternoon -cylinder3,dash light came on, had a cpl of spares in boot so changed at roadside no probs.Got home put it on VAG-COM and told me multiple misfires and cylinder 3 failure.Wiped codes and all was fine.Today we went out in car and,it just doesnt feel right,as though a coilpack has gone but not as severe,just crappy slight jerky running,theres no light on and checking vag-com no fault codes.Does this sound like another is about to go?
Also thought it could be maf related so disconnected maf,how should the car react? the engine stayed the same as though it didnt make a difference,is that maf dead or dying?

Had a quick look through and used search but couldnt find my problem (please redirect me if ive missed it)

My car only gets used twice a week so i started it up tonight to go out.She always starts first time but the last couple of times it rev's up to 1500 rpm ...stutters abit (between 5-10 secs) then settels down to just above 1000rpm(cold start ?) untill warm.Now it drives fine no prob's there...just wondered if this a earlly sign of a coil pack going ? (80,000 mile service due in 600miles) It had new plugs 2000 miles ago.

Any ideas would be cool.Thanks

Ok a small question - it would seem my coilpacks may be an issue but under closer inspection the wiring going to the packs is massively degraded 1 cable out of the conector going to one of the coilpacks is broken - how easy is it to replace the cables as i am sure that the others will follow suit soon. and does anyone know the part numbers for the cables and where they actually connect to at the other end?

Few questions

I have the juddering, burning and egg smell, but also have ecu light flashing
car is done 55. And not had issue before

does it sound like coil pack?

If so are there any guides to replacing

and what are the aftermarket ones like ... Cost too if poss

anyone know gsf prices?

Def the coil packs. That's what mine did. When you put it under load can you feel it judder?
Prices from gsf are ......( as above ) £25 plus vat each :)

Hi,mines always done that and I was led to believe its an auto choke warming the cat converter up so it better at dealing with exhaust pollution quicker.

Hi this is a very interesting topic and some brilliant posts by you guys, helped me in a million ways and appreciate it.
mate, everything vikingdin has written about his car not running right and not going above 120mph is the same as my car and that it judders etc, mine is doing the exact same, im not sure whether to change the plugs and all the coils as i changed the 3 of the coils earlier this year some time, or just to change the last remaining coil that i havent changed, should i even bother changing the plugs?
i wa salso asked by euro car part whether i would want the coil pack leads, what are the chances that could be my problem?

This evening I nipped out to Sainsburys and at one point noticed a slight eggy smell, which went away again after a few seconds. My car does sound a bit like a boxer engine at low revs altho I kinda put this down to having a big Jetex cone filter and this just being how it makes the engine sound.

Thing is it seems to be running fine from what I can make out it idles just fine and no juddering or hesitancy except a tiny bit when starting from very cold. Do coilpacks fail gradually or "just go"? I had new spark plugs put in about 3 or 4 weeks ago so I guess they're ok.

Just wondering if my coil packs are about to go. Around 1800 - 2200 rpm there is a slight judder / drop in power as I accelerate. It does not seem to make any difference if I boot it not, most of the time I am driving normally around town when it happens.

Also my diagnostics / emissions light came on today too, not sure if it related.

I have always had that drop in power at same revs as you,had when standard and still now when re mapped,dunno what it is,maybe turbo stall,I have changed all my coils so dunno.Maybe lazy MAF?

Hi Guys,

First post here (Been trying to post for over an hour maybe im just stupid!!!)...

Anyway long thing short. I have remapped my 03 Leon cupra 180bhp 68k yesterday at AmD.

As im driving home noticed the car jerks between 3-3.5k revs (40 miles round trip). Dont think its the remap as I read good reviews about them but wondering what it could be?

If i drive it below 3k revs its fine. I have been told by AmD to take it back if it persists. I was thinking it could be the coilpack as read that they gone after remap bit thats just a guess.

This is my first turbo and remap. Plus money is a bit tight at the moment so cant really afford trail and error.

Any help would be much appreciated,

Thanks.

Seems the judder is reducing??? Guess the car is adapting to new map. Anyway the car just is flying... Really happy with map just hope the judder disappears totally. Def recommend remap from AmD!!! Loving it!
